I would just like to add NÜOBELL as an alternative to the PowerBlock, as they're formed more like a regular dumbbell compared to the PowerBlock. Had mine for years, works just as good as on day one. Ultimately, doesn't really matter what your choice is as long as you're using them.
NÜOBELL is sold under the name SMRTFT[1] in the US, and as NÜOBELL in EU[2].
